Emoji Saver

The Emoji Saver for macOS animates emoji on your screen, drawing them from multiple brands (styles) of emoji, including Apple's as well as EmojiOne and Twemoji. Various effects are available, including "Bucket Party", where the screen is filled with emoji, "Patterns in the Rain", with emoji falling down from the top of the screen, "Words", where you can have your own words rendered by emoji, and several other effects. This is the free Lite version; to unlock all effects and features, you can buy the full version for approximately $3.50 USD.
